To investigate if uBH induced extensive air showers (EAS) can be distinguished from normal showers started by a primary particle, we performed simulations of uBH production and decay as well as EAS evolution processes. The former was done using a coupling of BlackMax micro black hole event generator and PYTHIA hadronization software, whereas the latter incorporated the use of EAS simulator CORSIKA.

COBISS.SI-ID: 3615227The dissertation investigates an alternative way to calculate grey-body factors in the large D-limit of general relativity for non-rotating micro black holes. Properties of possible signals of micro black hole decay that might be seen in the detectors were also investigated using the most recent Monte Carlo micro black hole event generators.

COBISS.SI-ID: 4073723It has been conjectured that Micro Black Holes (MBH) may be formed in the presence of large extra dimensions. These MBHs have very small mass and they decay almost instantaneously. Taking into consideration quantum effects, they should Hawking radiate mainly to Standard Model particles, this radiation then gets modified by the non trivial geometry around the MBHs; the so called greybody factors which filter the Hawking radiation. To test the validity of MBH models, one needs to investigate it experimentally. A primary tool in this investigation is simulation of the MBH formation and evaporation, including all theoretical work that has been performed up to now. BlackMax and CHARYBDIS2, are the most modern and realistic simulators currently available. However they still suffer from a lack of important parameters. In this article we will discuss the primary work that we have done to study the possible changes that can be implemented in the simulations.

COBISS.SI-ID: 3247099A selection of the Pierre Auger Observatory results on the study of the UHECRs was be presented, focusing on composition results. In particular, the measurements and the different roles of the observables with respect to mass composition was be discussed.

COBISS.SI-ID: 3551227The upgrade of the Auger Observatory will allow us to estimate the primary mass of the highest energy cosmic rays on a shower-by-shower basis. In addition to measuring the mass composition the upgrade will open the possibility to search for light primaries (and micro black holes) at the highest energies, to perform composition-selected anisotropy studies, and to search for new phenomena including unexpected changes of hadronic interactions. After introducing the physics motivation for upgrading the Auger Observatory the planned detector upgrade is presented.
